In the drawings the invention is illustrated in connection with' an automatic or semi- 85 automatic glassware forming machine of the general type shown and described in our application for .patent iled June 14, 1917, Serial Nd 172,678, and the invention is primarily intended for machines of such type, although 40 capable of use generally for glassware finishing machines having rotatable tables.

Machines of the type referred to are well known to the trade, and the parts of which shown in Figs. 1, 2 and 3, and diagramed in Fig. 6, are'deemed suiiicient to illustrate the relationship of our improvements thereto. Such machines comprise two vmold carrying tables, which rotate simultaneously, the molten glass being formed into blanks or parisons in the molds on the rst or blank form- Further aims and advantages of the in-4v ing` table, `and thence being transferred to the finishing molds on the second or blow table, from which the finished ware may be removed by suitable take-out means, all operating automatically. 'The dierent groups. of mechanlsms comprised in the machine are `actuated and coordinated by air lines controlled by suitable valves. In order that an adequate understanding of the take-out device may be had, it is needful that the con struction and operation lof the entire machine may be understood, and this may conveniently be describedy in the. following groups. V f

T able ww/ng mechanism n Referring to Figs. 1 and 2, the machine comprises two circular tables l0, 11, hereinafter designated blank mold and blow mold. tables, niountedfor rotation on pedestals 12,

13, which are supported .on a base 14. In order to bring the blanks 4successively to the several operating positions, or stations (see Fig. 1)- the tables are caused to turn intermittently in unison in the directionzof the arrows in Fig. 1, by means of a gear 16, which is mounted on a vertical shaft 17 journaled :on a pedestal 15 arranged between' the tables, and

,which meshes with gear teeth 18 formed around the lower edges of the tables. The shaft 17 is rotated intermittently by means of a splined gear'19 which periodically engages with a rack 20 on a piston rod 21 working in a horizontal cylinder 22 supported ou the base. The gear 19 is movable up and down by means of a hollow piston 23 in a vertical cylinder 24 which surrounds and supports the lower end of the shaft 17 (see Fig. 2). Upward movement of the piston 23 raises the gear 19 and disengages it from the disengagesv the locking pins from the tables to permit them to turn.

Blank mold and 'neck ring actuating devices r1`he blank mold table 10 is provided with six journals or brackets 30 for supporting the hollow shafts or carriers 31l (see Figs. 1 and 2) for the two part blank mold holders 32 and neck ring holders 33; and the blow mold table 11 is provided with six brackets 34 for supporting the two part blow mold hold- .ers 35 and adiustable bottom plate arms 36.

The blank molds 37 and neck rings 38 there'- for, and the blow molds 39 and bottom plates 40 therefor, are shaped to suit each different size and style of article, in conformitywith well understood practice.

The blank mold holders 32 and neck ring holders 33 are hinged to open and close on the vertical pins 41 (see Fig. 2) which are mounted in the outer ends of the hollow shafts or cylinders 31 to turn therewith. Twice during each revolution of the blank mold table these hollow shafts are caused to rotate one-half turn by any suitable means to invert the blank molds at the proper times for charging and blowing the blank; and the blank mold holders (and thereby the blank mol s and neck rings) are held closed during these movements by suitable means such as li (s 4 and yokes 43, which are mounted to slide in the hollow plungers 44. These plungers are mounted to slide in and turn with the hollow shafts 31, which are prevented from turning in the transfer position by the upper and lower guides 45 on the pedestal 12 between which their` inner ends slide. These plungers are operated by rollers on their inner ends which engage vthe stationary cam 46 on the pedestal 12. Springs 47 in the hollow plungers maintain the blank holders normally in closed position.

At the transfer position air operated means are provided for opening the blank mold holders 32, and neck ring holders 33 in proper sequence with the closing of the blow mold holders 35 as hereinafter described. For this purpose the inner end., of the plungers 44 (see Fig. 2) are fitted with studs 48 which at the transfer position project in the path of a radially movable finger 49 carried by a piston rod 50 mounted in a cylinder 51 on the top of the pedestal 12. At the proper time the piston 52, working in the cylinder 51 Withdraws the finger and stud in engagement therewith to pull back the plunger and open the blank mold holders as they reach the transfer position. Similarly the neck ring holders are opened at the proper time to release the blank or parison (see Fig. 2) by engagement of the stud 53 on the yoke 54, which operates them through the links 55,

with a grooved flange 56 carried by a piston rod 57-v working in a cylinder 58 mounted on the bracket 59 over the path of movement of the blank mold carriers.

Blow mold closing device The blow mold holders 35 (see Figs. 1 and 2) in the machine illustrated are hinged on vertical pins 60 mounted in the brackets 34, and are provided with spring pressed rods 61 adjustably connected to sliding yokes 62 actuated by cam rollers 63 to open and close the blow molds as hereinafter described. The rollers 63 engage a stationary cani 64 mounted on the pedestal 13 to hold the molds closed during the first half of the revolution of the table 11 from the transfer station. The blow molds 39 are open when they reach the transfer station, and followingthe opening of the blank molds 37 they are'closed by air operated means to embrace the blank, which is suspended during the interim by the neck rings 38 (as indicated in dotted lines in Fig. 2). The blow mold closing means preferably comprises a fork 65 secured to the radially movable piston rod 66 and arranged in the path of the cani rollers 63 to embrace a roller as the table stops with mold open at the transfer station. The piston rod 66 works in a/cylinder 6T, suitably disposed and mounted 611 the pedestal 13 so as to be actuated upon the opening of the blank mold to close the blow mold around the blank, as hereinafter described. The piston rod 66 also carries a stud 68 for actuating the oscillating valve 69 to admit air to the neck ring operating cylinder 58 to open the neck rings after the blow mold sections have closed around the blank, as hereinafter described in connection with Fig. 6.

The blow molds are securely held closed at the blowing station by clamping jaws 70 which engage lugs 71 on the blow mold holders. T he clamping jaws 70 are pivotcd on a support 72 and are actuated by means of toggles 'T3 connected to a piston rod 74 working in a cylinder 75, as illustrated in Fig. 1. Any suitable blow head 76 (see Fig. 6) may be used; and if'desirable two blow heads may be supplied, one at each blowing station. In case two blow heads are provided, the pressure of the air for blowing may bc adjusted by means of suitable regulating valves 77 (see Fig. 6) foreach blow head independently to suit differences in the ware o1' in the operating conditions.

Blow mod opening device llo ` tract them radially inwards.

carried by the piston rod- 84 having a pistonl which works in the cylinder (see Figs. 1

` The and the take-out station. This cam track has an initial inward sloping portion 80, the remainder of its course being substantially circular and normally arranged concentric with the axis of the table,iand when the rollers strike this sloping portion they are forced to ride inwards slightly and thereby slightly separate the mold holders to crack open the blow molds. The degree of opening of the molds may be controlled by adjusting the movable end of the. cam -78 inward by means of the slot 81 and holding screw82 (as indicated in Fig. 1).

If desired the amount of opening of thtl molds by the cam 78 may be increased to the extent necessary for removing the ware by adjusting the cam inward to the full limit of the slot 81; otherwise the molds are opened after they reach the take-out position by means of the hook or movable cam segment 83, which is positioned to engage the cam rollers 63 as they leave the track 79 and re- This hook is and 6) and is timed to operate in synchronism with the table rotating and locking devices as hereinafter described. This hook may be locked in its inner position by suitable means, such as a stop, to cooperate with the movable cam in its inward position of adjustment.

olds are opened wider and held open during 1ei-r movement from the take-out station to the transfer statin by means of a cam having a depending track 87 which en gages the cam rollers 63 and holds them at the inward end of their radial movement and guides them into the fork 65 at the transfer station .(-see Fig. 2).

Take-out defvz'ce and convey/0r The take-out device (see Figs. 1 and 3) for transferring the ware to the conveyor 8h consists of a gripping and lifting device and a swinging device to remove the ware from the open molds and deposit it on the conveyor.

ln the embodiment shown,'the take-out device consist o f a support, such as a bracket 89, which is rigidly attached to the base 14 and at its outer end is formed with a journal for a vertical shaft 90. The upper end of the shaft 90 is journaled in the outer end of a second bracket 91 suitably mounted upon some relatively7 stationary part of the machine. as-upon the cam 64.

` The take-out arm 92 is formed with bifurcate'd ends adapted to be clamped to the upper end of the shaft 90. Adjustment of the arm 92 vertically on the shaft may be effected b v an adjusting member suchA as a nut 93. whereby the take-out arm maybe raised or. lowered to accommodate glassware of various heights. The outer end of the arm 92 supports the vertically disposed cylinder 94 (see Figs. 3 and 5) which contains the piston 95 on the upper end of the piston rod 96. The lower end of the piston rod is T-shaped (see Fig. 5) and carries studs 97 working in slots 98 of jaws 99 that are pivoted to a cross pin which works in slot 101 of the piston rod and slot 102 of a depending double bracket 103. yThe piston rod 96 is counterbored as at' 104 to accommodate a spring and a plunger 106 interposed between the spring 105 and pivot pin 100, thereby to exert a downward pressure upon the pivot pin. The weightl of the piston is suiicient to hold the jaws in extended position normally as shown in full lines in Fig. 5. Gripping means such as plates 107 may be removably secured, asby bolts, to theou'ter ends of the jaws. l,

Normally the piston is in its lower position with the cross pin in the bottom of slots 102 in bracket 103, the jaws 99 and gripping plates 107 being held in upward open position against the tension of spring 105. Upward movement of the piston 95 and piston rod 96 raisesthe outer ends of the jaws 99,the

-- .pivot pin 100 being held stationary by the tension of sprin 105 bearing thereon, and thus causes the grlpping plates to swing together t9 grip the bottle under the finish as shown in dotted lines in Fig. 5l As the piston rod continues its upward movement the lower end of the slot 101 in the piston rod engages the pivot pin 100 and lifts it upward thereby lifting the bottle off of the bottom plate of the mold.

-On the return downward movement of the piston rod the bottlev is lowered until the pivot pin 100 engages the'bottom of the slot 102 in bracket 103. Further downward movement compresses the spring 105 in counterbore 104 of the piston ro-d thereby to hold the pivot pin in the lower en-d of the slot 102 while the gripping plates are swung upwardly and outwardly away from the ware.

Our invention contemplates the provision of novel means to swing the take-out arm in an arcuate path from a. position over the mold to a position remote therefrom, as over a conveyor, and in the embodiment shown in the drawings an operating arm 108A is suitably attached to the shaft 90, as by a clamp 109 (see Figs. 3 and 4). The free end of the arm 108 isforme'd with a vertically disposed cylinder 110 in which a piston 111 works carrying a piston rod 112 (see Fig. 2). A roller 113 is mounted upon the upper end of the piston rod 112- for engagement with lugs 114 secured to the under side of the rotating mold table 11, there being one lug 114 foreach of the molds carried by the table. Air is admitted from a suitable source, hereinafter described, into the cylinder 110 through the port 115 at the lower end, to move thetroller up in front of the lug 114 at the position A (see Fig. 4). Movement of the table swings the arm 108 to position B and thereby the take-out arm 92 from position C to D (see Fig. 1). When air is admitted to the top of cylinder 110 through port 116 the roller is lowered out of engagement with the lug 114.

l In order to provide an adjustment for the arm 108 so that the roller will be in proper position relative to the lug 114 when the table is at rest, the arm 108 (see Figs. 1 and 4) as shown, is formed with a-lug 117 carrying an adjustable stop screw 118 adapted for engagement with a lugl 119 on the stationary -arm 89.

This screw 118 engages the lug 119 at the end of and limits the return swinging movement of the arm 108. Y

Our invention further contemplates the provision of means for returning the take-out arm'to its normal position over a mold 'after it has been swung away'to remove the ware, and also for cushioning the return stroke. In -the form of machine shown in the drawings, a lever 120 is securely fixedto the lower end of the shaft 90 by suitable fastening means, as by a clamp 121, one end of the lever being connected to a spring 122 (see Figs. 1 and 4) the other end of which is attached to a lug 1'23 on the .base 14 yof the machine. Any suitable means may be provided to conneet the end of the lever 120 to the spring 122 but preferably an adjustable connection is provided. ln the form shown, the end of lever 12() is bifurcated and formed withl transverse arcuate seats 124 to receive the trunnions 125 of a swivel block 126 loosely surrounding an adjusting screw 127 attached to one end of the spring 122. vAn adjusting nut 128 is threaded upon the screw 127 and ahuts against the swivel block 126 to effect adjustment of the s ring.

lhe opposite end o the lever 120 is pivotally connected, as at 129, to a piston rod 130 carrying a piston 131 workin in a cylinder 132 open at one end.' The cyhnder is mounted on a pivot'133 betweensiaced \1ugs 134 in order to accommodate itsel automatically to the varying ositions of the piston rod130 due to the rocling movements of the lever 120. A restricted escape port is provided in the cylinder 132 near the closed end thereof to check the escape of air trapped between thepiston and closed end of the cylinder, thereby to cushion the return movements of the arms 92vand 108. As the arm 108 is moved from osition A to B (Fig. 4) by the movement o the lugs 114 on the table, the shaft 90 and lever 120 rotate clockwise (Figs. 1 and 4) to extend the spring 122 and move the piston 131 towards the open end of the cylinder` 132. When the rollerr 113 is withdrawn from engagement with the lug 114, the spring contracts and swings the arms '92 and 108 back to their normal position. l*This return movement is, however, cushioned by means of the air trapped between the piston 131. and closed end of the cylinder. Our invention further contemplate thel provision of means for operating the improved take-out mechanism in proper timed relation to the operation of the other parts of a glassware forming machine, as diagramed in Fig. 6. In this diagram air pressure mains and parts connected thereto are marked M, exhaust air ports opening into the atmosphere are marked EX, and the air pipes are indicated by the full lines upon which the direction of flow to actuate the various movements is indicated by arrows. The parts are shown in the positions which they occupy after completing the automatic cycle of movements and ready for another charge of glass.

Starting Upon delivery of a charge of glass to the blank forming mold, the'gatherer, by trip` ters with a groove 140 around the pin when `ing machine if desired.

Movement of the main valve 138 to the right as shown in Fig. 6 will admit air from the pressure main M to the left hand end of the table rotatino cylinder 22 and return the piston and rac 21 secured thereto to position for engagement with the gear 19 splined to shaft 17 for rotating the tables through gear 16. As the rack approaches the end of its return movement, it will move the finger 142 on the valve 143 to shift the latter to the right. This finger enga es in a slot 144 on the under side ofthe r'ac This slot is a little shorter than the movement of the rack so that the finger 142 and the valve 143 are moved just before the' end of the movement of the rack in either direction. Springs 145 between the valve and ends of the valve casing enable the valve vto over travel a little at each end of its stroke without detriment, and an adjustable screw 146 in rthe head vend of the cylinder 22 limits the the latter is in locking position. Thus, if for any rea-son, the locking pins should not be4 travel of the piston at the head end of the stroke and positions it so the gear 19 may drop into the rack21 without difficulty.

Simultaneously with the admission of .air to the line 137, air is admitted into the line 147 leading to a'blow down actuating cylinder 148 which is actuated to swing the blow dowl. cylinder 149 over a blank mold and also admit air to the top of the blow down cylinder 149 to move the blow down head down to engagement with the top of the mold.

Movement of the control valve 143 by the ret-urn of the piston in the cylinder 22 at the end of its return stroke as hereinbefore described admits air from the pressure main M through said valve to the line 150 and opens the pipe 151 to the atmosphere, for unlocking the moving parts of the machine preparatory to the table rotating movement.

Air from the pipe 150 will .pass into the upper endl of the cylinder 24 and lower the hollow piston 23 and splined gear 19 to engage the. rack 21, and at the same time withdraw the locking pins 25( and 26 from the tables, thereby admitting air from the pressure main M through the housing 28a surrounding the locking pin 26 to the pipe 152 and opening the pipe 153 through the housing. surrounding the locking pin 25 to the atmosphere. The pipe 150 also leads to the control valve 136 to return it to normal posi tion when air is admitted to it. y,

The pipe 150 also leads to a port 154 in the take-out arm 92 which admits air to a Vcarry the molds to their succeeding operating roller 113 infront of the table lug stations. This pipe 152 also leads to the port 1-15 in the cylinder 110 to position the 114. Part of the air admitted by the locking pin valve to the pipe 152, after passing through the neck pin 'actuating ,cylinder 156 p to withdraw the neck pin from the blank mold in the charging position,(as is more fullyv shown and described -in'our applicationfiled June 4, 1917) is returned to the pipe 157 when the neck pin is withdrawn' and the groove 158 in the lstem/registers with theports valigning with the pipe 157. The pipe 157 leads to the right handend of the main valve 138 to throw the valve to the left back to normalposition and admits air from the pressure main M to the right hand endof the table rotating cylinder 22 as shown in Fig. 6. Thus the piston and piston ro'd 21 are moved to the left to actuate the rack 20 and gears 19 and 16 to rotate the tables through the angle of 60 and thereby shift the blank mold and blow mold from one operating station to the next. The lugs 114`on the under side of the rotating blow mold engage the rollers 113 and cause the take-out arm 92 to be swung from the pov sition C to D (Fig. 1) where it is positioned ,75 above a suitable conveyor. y

Upon the completion of a table turning movement of the rack 20, the valve 143 will be shifted to the left (as shown in Fig. 6)

to admit air from the pressure main M to the pipe 151 and to open the pipe 150 to the atmosphere. This will raise the piston 23, vwithdraw the splined gear 19 from the rack 20, and lift the locking pins 25 and 26, to

lock the tables. Pipe 151 leads to port 160 S5 in take-out arm connected to passage way. 161 leading to upper end of take-out cylinder 94 to move the cylinder downward and deposit the bottle upon a conveyor or other support.

The air admitted to the pipe 151 at the end of the turning movement of the table rotating cylinder also actuates the blank mold opening cylinder 51 and the blow mold closing mechanism.

Shifting the locking pins to lock the tables opens the pipe 152 to the atmosphere through the valve in the pin 26 and also admits air from the pressure main through the valve in the pin 25 to the pipe 153 thereby actu' ating the mold clamps and blow heads to engage the mold and perform the several orming and blowing operations, as will be understood by those famili-ar with machines of the same general type now in use. For example, the blow head cylinder 155 is fitted with a piston and depending piston rodl 162 having the blow head 163 at its lower` end. A vented check valve 164 in the pipe 151 preventsltoo rapid descent of.the 'blow head. Air is piped from the pressure main M through the adjustable pressure reducing valve 77 to the blow head, which has a vertically slidable inverted cup shaped Contact piece 165 adapted to engage with and form an air-tight joint onthe top of the blow mold surrounding the. neck' ofthe ware as the blow head descends. Further lowering of the blow head `will cause relative upward movement oftheV contact piece thereon to 120 open the air valve 166 and admit air tothe ware in the blow mold to blow it to finished shape. When the tables are unlocked at the close of the blowing operation, the reversal .of pressure in the pipes 152 and 153 will lift theJ blow head and 'shut oil further supply of air to the valve 166 by its dropping on to its seat. While this.operation is taking e'ect, air from the line 153'passes tothe port 116 inthe upper end of the cylinder 110 to lower the roller 113 out of engagement with the lug 114 on the under side of the blow mold table, and pcrmitthe spring 122 to return the take-out device to its normal position as shown in Fig. l.

The conveyor 88 (see Fig. 1)v is of the link belt or other suitable form, and preferably is operated by means of a ratchet wheel 167 (see Fig. 6) that is attached to one of the belt carrying pulleys and is engaged by a pawl 168 on an oscillating lever 169. The conveyor is operated with a step by step movement by an air cylinder 17() and piston, the piston rod 171 of which is connected to the lever 169 by a pin 173 working in a slot 174 in the lever, or other suitable connection. A screw 175 in the end of the cylinder 170 enables. the stroke of the piston to be adjusted to the lengthof travel of the conveyor desired for the size of ware being manufactured.

During the time that the tables are locked by the locking pins 25 and 26, the conveyor actuating mechanism is being returned to normal position, shown at the lower left hand side of Fig. 6, by air from the pipe 153. An adjustable check valve 176 is provided for the pipe 177 which connects the head end of the cylinder with the pipe 153 for choking the exhaust and thereby controlling the speed of the working stroke of the conveyor operating devices; anda stop cock 178 is arranged in the pipe 179 which connects the outer end ofthe cylinder 170 with the pipe 152 whereby the speed Aof returning the conveyor actuating mechanism may be controlled.

When the locking pins 25 and 26 are'released from engagement with the tables, air is admitted into pipe 152 passing to pipe 179 to move the piston forward in the cylinder 170, thereby moving the conveyor forward, to make room for the next bottle deposited thereon by the take-out mechanism.

Summarizing the operation of the takeout device in connection with an illustrative machine (see diagram Fig. 6) it will be observed that when the piston'that operates the rack 20 for intermittently rotating the tables reaches the right hand end of the cylinder 22 at completion of its idle stroke, the'valve 143 is tripped admitting air into lthe line 150 to actuate the piston in the cylinder 94 to grip and raise the bottle oiiz of the bottom plate of the mold. At the same time,- air is admitted to the cylinder 24 to lower the piston 23 and withdraw the locking pins 25 and 26 from engagement with the moldI carrying tables. Air from the pressure main M then passes through the valve in the casing surrounding the locking pin 26 into the pipe 152 to admit air into the lower 'end of the cylinder 110 to raise the roller 113 into position in front of the lug 114 on the under side of the blow mold table. .'Simultaneously, air is admitted to the top of the neck pin cylinder 156 to lower the neck pin out of engagement with the blank mold. As the neck pin is lowered, a groove 158 on thel stem registers with the portin the housing leading to pipe 157 and admits air into the right hand end of the main control valve 138, thereby moving the valve to the left as shown in Fig. 6, and thus air from the main pressure line M is admitted to the rear of the cylinder 22 to move the piston and rack 20 to the left to rotate the table. Rotation of the table moves the take-out arm 92 and the bottle held by the gripping members 107 from the .position C to the position D, preferably over a conveyor 88 of any suitable type as shown in Fig. 1. When the rack 2O completes its table rotating stroke the valve 143 is tripped, thereby exhausting air from the line 150 and admitting air from the main pressure line M throu h the pipe 151 to lower the piston in the cy inders 94 and drop the bottle upon the conveyor. At the same time air is admitted into the upper end of the cylinder 23 to disconnect the rack 20 from the pinion 19 and raise the locking pins 25 and 26 to lock the tables. Air in line 152 is then permitted to exhaust through the valve surrounding locking pin 26, while air is admitted from the main pressure line M in the valve surrounding locking pin 25, to the line 153 to lower'the roller 113 out from engagement with the lug 114. The take-out arm 92 and arm 108 are then quickly returned to their normal positions by means of the spring 47.
